I hope someone can help me out here i have had a S type 4.2 V8 for approx 18 months now and although they dont affect the general performance of the car ia have three little faults that need correcting.1) A/C does not work,i had it regassed and no leaks were found but still wont work.I had someone mention something about flaps? Any ideas anyone? 2) The reverse audible warning sort of works but instead of goin beep beep beep and getting faster when approaching an obsticle it just makes on continuous beeeeep.3)And last but not least my nearside (passenger side) door mirror has stopped working on the electric button.I can adjust it manually and the drivers side mirror works as normal. If anyone can help please!
